Chimpanzees are one of the closest living relatives of humans, sharing approximately 98% of our DNA. ¹⁾

There are two species of chimpanzees: the common chimpanzee (Pan troglodytes) and the bonobo (Pan paniscus). ²⁾

Chimpanzees are social animals and live in communities that can range in size from 15 to over 150 individuals. ³⁾

Chimpanzees are known for their intelligence and are able to use tools, solve problems, and communicate with each other using a complex system of vocalizations, gestures, and facial expressions. ⁴⁾

Chimpanzees are omnivores and their diet consists of a variety of foods including fruits, leaves, insects, and sometimes small mammals. ⁵⁾

Chimpanzees have opposable thumbs and can use their hands to grasp and manipulate objects. ⁶⁾

Chimpanzees are sexually dimorphic, meaning that males are larger than females. Adult males can weigh up to 130 pounds, while females typically weigh around 80 pounds. ⁷⁾

Chimpanzees are capable of empathy and have been observed consoling and comforting other members of their group. ⁸⁾

Chimpanzees have complex social hierarchies and individuals can form long-lasting bonds with each other. ⁹⁾

Chimpanzees have been observed using different types of tools for various purposes, such as using sticks to extract insects from tree bark or using rocks to crack open nuts. ¹⁰⁾

Chimpanzees are capable of recognizing themselves in mirrors, which is a sign of self-awareness. ¹¹⁾

Chimpanzees have been known to engage in violent behavior, including attacks on other chimpanzees and even humans in some cases. ¹²⁾

Chimpanzees are found in the wild in several African countries, including Tanzania, Uganda, and the Democratic Republic of Congo. ¹³⁾

They are listed as endangered on the IUCN Red List of Threatened Species. ¹⁴⁾

Chimpanzees have been the subject of extensive research, including medical research and studies of their behavior and cognition. ¹⁵⁾
